Passive Mechanical Screwing Device

Abstract

The invention provides a passive mechanical screwing device, which belongs to the mechanical field and includes four pressing plates, a first ratchet transmission mechanism, a second ratchet transmission mechanism, a multi-link mechanism, a planetary gear acceleration mechanism, and multiple groups of elastic guide mechanisms And twist the cape. The second ratchet of the second ratchet transmission mechanism and the first ratchet of the first ratchet transmission mechanism are set at 90° in the initial state; the multi-link mechanism includes a first linkage assembly, a second linkage assembly and a plurality of intermediate links Rod; the first ratchet of the first ratchet transmission mechanism is coaxially connected with the planetary gear of the planetary gear acceleration mechanism through a coupling, and the second ratchet of the second ratchet transmission mechanism is co-located on the planetary gear. The invention provides and designs a double ratchet transmission mechanism to convert the reciprocating motion of the multi-link mechanism into a continuous rotary motion of screwing the cape; two pairs of pressure plates are provided, and force can be applied from two directions, which is convenient to operate and saves time and effort .

Description

technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to a passive mechanical screwing device. Background technique [0002] Teleoperated manipulators are widely used in military, marine, aerospace and other fields, and screwing the target is a common requirement for teleoperated manipulators. At present, there are still deficiencies in the screwing operation of the remote operation manipulator: on the one hand, in the working environment where manpower is not accessible, the remote operation manipulator has the screwing ability by replacing the end effector, and the repetitive disassembly and assembly operations are time-consuming and complicated. Problem; on the other hand, because the screwing operation requires high coaxiality, and the remote operation often has large errors, it is difficult to guarantee the operation accuracy of conventional tools, and improper operation may even cause equipment damage.

At present, there are still deficiencies in the screwing operation performed by the remote operation manipulator: on the one hand, in the working environment where manpower is not accessible, the remote operation manipulator has the screwing ability by replacing the end effector, and the repetitive disassembly and assembly operations are time-consuming and complicated. On the other hand, because the screwing operation requires high coaxiality, and there are often large errors in remote operation, it is difficult to guarantee the operation accuracy of conventional tools, and improper operation may even cause equipment damage
